survival part of the brain. This is not the part of the brain that handles personality‚ morality or conscious choice. That processing takes place in the cerebral cortex. The cerebral cortex is supposed to be able to overcome the overwhelming impulses of the midbrain. But in addiction‚ a defect occurs and the midbrain becomes bigger than the cortex and then therefore it takes over. Brain changes over time make it hard for one to maintain self-control.

Anna’s angst is a prominent factor influencing her rushed decision.

New theory on consciousness Abstract There has always been a clear distinction between what is considered rational thought and emotional behavior. The classical view is that rational thinking is more evolved than being emotional therefore the cortex‚ as a superb product of the evolution of brain must be responsible of the rational part of the self and the thalamic system‚ the one we share with birds and lizards must be the responsible of the emotions we feel. Nobody doubts that the thalamic

The matosensory area is located in the parietal lobe of the brains cerebral cortex. It receives and translates the sensory information from our skin and body. Which is how we are capable of locating where and what is happening to our bodies. The matosensory area locates the action but is not responsible for our emotional

Brain Drugs can alter important brain areas that are necessary for life sustaining functions and can drive the compulsive drug abuse that marks addiction. Some of the areas affected by the brain are the brain stem‚ Limbic system‚ and cerebral cortex. The brain stem controls basic functions critical to life‚ such as heart rate‚ breathing‚ and sleeping. The limbic system contains the brain’s reward circuit it links together a number of brain structures that control and regulate our ability
